In situations where the net and gross fund expense figures are different, the investment manager has contractually agreed to limit the investment option's expense. Differences may also be shown due to the investment manager choosing to pay certain expenses that would normally be payable by the fund. The gross fund expense figure does not reflect any waivers or caps on the fund. Performance when shown reflects the application of net expenses of the fund.

Returns represent past performance and do not guarantee future results. Share price, principal value, and return will vary and you may have a gain or loss when shares are sold. Current performance may be lower or higher than quoted. For more performance information, including the most recent month-end performance, visit principal.com.

  ^** If an investment provider chooses not to participate in the Principal® Platform Connectivity Program (Program), your Plan may be charged an annual Program fee of $1,000 to be included as part of your Principal® recordkeeping fee. This Program fee helps to pay for a number of expenses incurred in connection with maintaining and adding investment options to our platform, including but not limited to, expenses for IT systems and staffing needs and required legal and compliance services. The appropriate plan fiduciary may remove the investment option(s) associated with the Program fee, at any time, by contacting Principal with the investment option change. Changes related to the plan's investment options could change overall plan fees.

Investing involves risk, including possible loss of principal.

Fees and expenses are only one of several factors that participants and beneficiaries should consider when making investment decisions. The cumulative effect of fees and expenses can substantially reduce the growth of a participant's or beneficiary's retirement account. Participants and beneficiaries can visit the Employee Benefit Security Administration's website for an example demonstrating the long-term effect of fees and expenses.

Several investment companies have decided to impose redemption fees and/or transfer restrictions on certain plan and/or participant transactions. One or more of the investment options in your employer's retirement plan may be impacted. For more information, log into your account and visit us at at principal.com.

Investment Types
Short-Term Fixed Income - This asset class is generally comprised of short-term, fixed-income investment options that are largely liquid and are designed to not lose much value. These investment options may include stable value, money market, short-term bond, and guaranteed interest accounts. They are considered to be among the least risky forms of investment options. However, they typically have a lower rate of return than equities or longer-term fixed income investment options over long periods of time. Depending on the objectives of the investment options, they may experience price fluctuations and may lose value.
Fixed Income - This asset class is generally comprised of investment options that invest in bonds, or debt of a company or government entity (including U.S. and Non- U.S.). It may also include real estate investment options that directly own property. These investment options typically carry more risk than short-term fixed income investment options (including, for real estate investment options, liquidity risk), but less overall risk than equities. All investment options in this category have the potential to lose value.
Balanced/Asset Allocation - This asset class is generally comprised of a combination of fixed income and equity investment options. These investment options may include balanced, asset allocation, target-date, and target-risk investment options. Although typically lower risk than investment options that invest solely in equities, all investment options in this category have the potential to lose value.
Large U.S. Equity - This asset class is generally comprised of investment options that invest in stocks, or shares of ownership in large, well-established, U.S. companies. These investment options typically carry more risk than fixed income investment options but have the potential for higher returns over longer time periods. They may be an appropriate choice for long-term investors who are seeking the potential for growth. All investment options in this category have the potential to lose value.
Small/Mid US Equity - This asset class is generally comprised of investment options that invest in stocks, or shares of ownership in small to medium-sized U.S. companies. These investment options typically carry more risk than larger U.S. equity investment options but have the potential for higher returns. They may be an appropriate choice for long-term investors who are seeking the potential for growth. All investment options in this category have the potential to lose value.
Global/International Equity - This asset class is comprised of investment options that invest in stocks, or shares of ownership in companies with their principal place of business or office outside the United States. These investment options often carry more risk than U.S. equity investment options but may have the potential for higher returns. They may be an appropriate choice for long-term investors who are seeking the potential for growth. All investment options in this category have the potential to lose value.
